SPECIFICATION forming part of Letters Patent No. 626,343, dated June 6,1899.

Application filed December 29, 1898.. Serial No. 700,588. (No model.)

To all whom it may concern.-

Be it known that I, BYRON PHELPS, a citizen of the United States,residing at Seattle, county of King, State of Washington, have inventedcertain new and useful Improvements in Locks, of which the following isa full, clear, and exact description.

My invention relates to looks; and my ob ject is to improve theconstruction of the same.

In the accompanying drawings, showing the preferred embodimentofmyinvention,Figure 1 shows a plan view, parts being in section, of mylock applied to the stile of a door. Fig. 2showsahorizontalsectionalviewthereof. Fig. 3 shows a vertical sectionalview on the line X X of Fig. 2 looking as the arrows fly. Fig. 4 showsthe broad roll-back. Figs. 5 and 6 show details of the outer knob andspindle. Fig. 7 shows the frame of the lock in plan view. Fig. 8 shows avertical section on the line' Y Y of Fig. 2 looking as the arrows fly.Fig. 9 shows a detail of the inside knob and spindle. Fig. 10 shows thelocking-rod. Fig. 11 shows the connecting-rod between the lock in theoutside knob and'the narrow roll-back. Fig. 12 shows the narrowroll'back. Fig. 13 shows a side elevation of the outer knob, thepintumbler lock therein being shown in dotted lines.

This embodiment of my invention is intended to be inserted in a notch inthe stile of the door, following out the general lines in this respectof my former application, filed March 10, 1897, renewed December 5,1898, Serial No. 698,371.

In regard to the present embodiment of my invention it will be observedthat the knobs and spindles are offset. It often happens that the stileof a door is so narrow that a deep notch cannot be cut therein withoutmaterially weakening the same; but yet it is disadvantageous to bringthe knobs very close to the edge of the door, because when the door isshut the outside knob would pass so close to the jamb that a personshand on the knob would probably be caught between the knob and the jamband injured. This objection is not present with respect to the innerknob, because said knob does not pass said jamb at any time. To givegreater clearance between the knob and the jamb, and thereby avoid theof two parts, as shown.

danger of thus injuring the hand, I offset the outside knob, as shown.

Referring to the drawings, A represents a frame, preferably formedintegral and having spindle-bearings B O and projecting faceplate a.Over these spindle bearings are slipped side plates or escutcheons Z) c,relatively adjustable toward each otherfor instance, by the screw b -soas to clasp the sides of the stile of the door, as set forth in my saidformer application.

D is a latch-bolt working in an aperture in the face-plate a and pivotedat (Z.

E is a shoe having a yoke e pivotally connected to the latch D by aconnection d. This connection has a lug (1 between which and a lug a onthe frame is a spiral spring a tending to press this latch connectionand shoe outward, as shown in Figs. 1 and 2.

B is a knob, preferably having a hollow spindle attached to the innerside of the head thereof and rotatably supported in the spindle-bearingB. This knob may be formed To the inner end of this spindle b is fixed,by dowel-pins b, a roll-back b which has lugs b thereon which contactwith lugs e on shoe E to retract the same, and consequently the bolt D.F is a second shoe narrower than said first shoe E, lying alongside thesame and havinga slot f therein, into which projects a lo g e on shoe E.Shoe F has also a hole f therein opposite a hole a in the relativelystationary frame when said shoe is in its normal position of rest. ShoeE has an elongated slot (2 therein, extending, when said shoe is at itsnormal position of rest, over the holes f and (1 as shown in Fig. 2.

G is a second knob, preferably formed in two parts, the part g havingthe spindle g and the other part 9 forming a cap suitably attached tosaid part gforinstance, by screws, as shown-and hollowed out to inclosea look, if desired. The general features of this knob and inclosed-lockconstruction are claimed in my former application, Serial No. 699,891,filed DecemberfZl, 1898. This spindle g has a tongue on the end thereof,as shown in Fig. 6, over which fits a broad-face rollback II, which hasa slot h and shoulders 72/ h. This roll-back may be fastened to thespinpreferably of the familiar pin-tumbler kind,

in which one part K constitutes the casing and which has an inner part7c, which is normally locked to the casing by the pin-tumblers, butwhich may be rotated by the insertion of a suitable key, as in saidformer application. The casing of this look is fixed relatively to theknob G by projections as shown, so that it will rotate with said knob,but will be always in fixed relation thereto.

The part 70, which I designate the key-bar rel, has a key-slot 70exposed by the opening g in the cap 9 By the insertion of the key intothis key-barrel the pin-tumblers will be raised and the key-barrel maybe rotated relative to the casing and knob, as is usual in this class oflocks. This key-barrel may carry on the end thereof a lag W, to which'isattached a rod L, (shown in detail in Fig. 11,) reduced at its inner endZ to fit the hole in roll-back M andthreaded. Over this reduced innerend is slipped a narrow roll-back M, which is held to the end of thisrod by any suitable fastening means, such as a nut Z. This roll-back isfixed to this rod, is rotatable therewith, and has the usual shoulders mthereon. The roll-backs H and M prefer-ably have their shoulders inalinement and contact at the same time with the yokes e and f on theshoesEand F, as shown in Figs. 3 and 8. It will be evident that bothroll-backs will normally be operated when knob G,and consequentlyspindleg, is turned, and will therefore throw back both ,of the shoes, andconsequently the latch-bolt D. The wide roll-back H extends from incontact with the narrow shoe F across into contact with the wide shoe E;but the roll-back M contacts only with the wide shoe E. The broadroll-back H is firmly fixed to spindle g and act-uates shoe F, whichcontacts at the rear ofslotftherein with lug e on shoe E. Rotating gtherefore would throw back shoe E, and consequently latch D, even ifrollback M were not present, and this construction of spindle g,roll-back H, and shoe F takes most of the strain off from rod L,rollback M, key-barrel k, and the pin-tumblers k when knob G and spindleg are rotated. This prevents the relatively weaker latchoperatingmeansnamely, key-barrel 7c, rod L, and roll-hack M-from being strainedat every rotation of knob G and spindle g, and

consequently loosened.

N is a locking-rod held inside the hollow spindle b so as to belongitudinally movable therein and is pressed inwardly by the spiralspring 11 in said spindle. The locking-rod has a pin '11 projecti-n glaterally therefrom through a slot in bearing B and a slot n in spindle12 as shown in Figs. 1, 7, and 9. O is a rotatable finger-cam preferablyheld outside this spindle b and bearing 13 and against shoulder 12 onthespindle-bearing, as shown. The finger-piece has a cam-face abuttinghole a in the frame.

against the pin it. By the rotation of this finger-cam the pin it, andtherefore the locking-rod, may be moved outward and allowed to be movedinward by the spring a. This locking-rod has a projection n in the innerend thereof, which preferably passes into a longitudinal slot 6 in theshoe E.

It will now be evident that when knob G is turned both roll-backs willbe rotated and both shoeswill be retracted. When however, the finger-camO is rotated, the spiral spring will press the locking-rod N inward orto the right in Fig. 2 and the projection 11 will pass through the holef in shoef and pass into the This will lock shoe F from retraction; butthe shoe E may still be drawn back, because the slot 6 therein allows amovement of said shoe in spite of projection 01 When the locking-rodthus locks the shoe F, the knob G and spindle g cannot be rotated,because the shoulders h on roll-back g abut against the lugs on theyokes f of the locked shoe. This results in locking the knob fromrotation. By the insertion of a key, however, into the key-barrel thesame may be rotated inside ofthe knob,which would rotate the rod L androll-back M, which in turn will retract shoe E, and consequently latchD. In this way the door may be opened, although the outside knob G isfixed and the door locked in respect to it. The inner knob B can operatethe shoe E, and consequently the latch D, at any time, as said shoe ispreferably not at any time locked.

It will. be obvious that many changes may be made in my constructionherein shown without departing'from the spirit of my invention.
